Actually that is irrelevant for what the govt has in mind, namely a few colocation places around the country that ISPs interconnect with either via fibre or ethernet if they are in the same datacentre, with rings of fibre round most cities and most DSL tails for 1 or more states being terminated in cities this is trivial to do, although this is where the squabbling over funding for those not able to interconnect via ethernet begin, and who pays for the fibre interconnects etc.richary wrote:The problem being that internet traffic does not flow in or out of Australia via a common point where the government could place a filter. There are multiple entry/exit points from the country.
Though the technical detail on how it might be achieved is irrelevant, the issue is how best to stop it happening in the first place.
Also most fibre into and out of Australia is via 2 places, Sydney and Perth, so it would be easy to trap exit/entry points. Look up the maratime exclusion zones for boats and where they aren't allowed to anchor round Australia there is only the above 2 cities covered from memory.
According to http://www.amsa.gov.au/Shipping_Safety/Marine_Notices/ these 2 are the most current/only ones existing to protect cables.

I guess the funny thing is, there is no protection zone for any tassie cables, but they are domestic, but yea
